Published Breakthrough in organic semiconductor synthesis paves the way for advanced electronic devices
(via sciencedaily.com)
Original source 
A research team has achieved a significant breakthrough in the field of organic semiconductors. Their successful synthesis and characterization of a novel molecule called 'BNBN anthracene' has opened up new possibilities for the development of advanced electronic devices.
Published Molecules exhibit non-reciprocal interactions without external forces
(via sciencedaily.com)
Original source 
Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don t seem to follow this reciprocal law.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com)
Original source 
Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published How technology and economics can help save endangered species
(via sciencedaily.com)
Original source 
A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Novel catalyst system for CO2 conversion
(via sciencedaily.com)
Original source 
Researchers are constantly pushing the limits of technology by breaking new ground in CO2 conversion. Their goal is to turn the harmful greenhouse gas into a valuable resource. A novel catalyst system could help reach that goal.
Published Insects already had a variety of defense strategies in the Cretaceous
(via sciencedaily.com)
Original source 
Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published How national policies affect forests in border regions
(via sciencedaily.com)
Original source 
How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting
(via sciencedaily.com)
Original source 
Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.
Published One small material, one giant leap for life on Mars: New research takes us a step closer to sustaining human life on the red planet
(via sciencedaily.com)
Original source 
Researchers have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.
Published Finding new ways to adapt to a growing weather threat
(via sciencedaily.com)
Original source 
Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.
Published Reduced air pollution during pandemic points to way to preserve Himalayan glaciers
(via sciencedaily.com)
Original source 
Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.
Published World's smallest 'fanged' frogs found in Indonesia
(via sciencedaily.com)
Original source 
Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.
Published New strategy reveals 'full chemical complexity' of quantum decoherence
(via sciencedaily.com)
Original source 
Scientists have developed a method to extract the spectral density for molecules in solvent using simple resonance Raman experiments -- a method that captures the full complexity of chemical environments.
Published Unveiling molecular origami: A breakthrough in dynamic materials
(via sciencedaily.com)
Original source 
A research team has unveiled a remarkable breakthrough in the form of a two-dimensional (2D) Metal Organic Framework (MOF) that showcases unprecedented origami-like movement at the molecular level. This pioneering study represents a significant leap forward in the field of dynamic materials, while also hinting at futuristic applications in metamaterials and quantum computing.
Published Scientists tackle difficult-to-recycle thermoset polymers
(via sciencedaily.com)
Original source 
A team of scientists has got a step closer to making several different types of plastic much easier to recycle, using a method that could be applied to a whole range of difficult-to-recycle polymers, including rubbers, gels and adhesives.
Published Little bacterium may make big impact on rare-earth processing
(via sciencedaily.com)
Original source 
A tiny, hard-working bacterium -- which weighs one-trillionth of a gram -- may soon have a large influence on processing rare earth elements in an eco-friendly way.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com)
Original source 
Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com)
Original source 
Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published For this emergent class of materials, 'solutions are the problem'
(via sciencedaily.com)
